3-Preventative Maintenance
Regular Maintenance Activities
Cleaning Your Treadmill- When cleaning your treadmill spray amild*
cleaning agent, such as awater and dishsoap solution, on aclean cloth first,
and then wipe the treadmill with the damp cloth.
!CAUTIONS: Do not spray cleaning solution directly on the treadmill.
Direct spraying could cause damage to the electronics
and may void the warranty.
*Using a non-recommended cleaning solution can cause
damage to your treadmill. Do not use an alkaline cleaner
to clean your treadmill. Read the label on the cleaning
product before you use it. If the ingredients list alcohol or
say "
no
t recommended for aluminum II do not use that
product.
!WARNING: To prevent electrical shock, be sure that power is shut off
and the treadmill is unplugged from the electrical outlet
before performing any cleaning or maintenance
procedures.
Use the following routine to help insure your treadmill's long life:
After Each Use -Wipe up any liquid spills immediately. After each
workout, use adamp cloth to wipe up any remaining perspiration from the
handrails and painted surfaces.
Be careful not to spill or get excessive moisture between the edge of the
display panel and the console, as this might create
an electrical hazard or
cause failure of the electronics.
!WARNING: Keep wet items away from inside parts of the treadmill.
Electrical shock could occur even if the treadmill is
unplugged.
Every Month -Vacuum any dust or dirt that might accumulate under or
around the
600T. Motors are especially susceptible to dust and dirt, and
restricted airflow can prevent adequate cooling that could shorten
motor life.
To clean the motor components, you must remove the two Phillips head
screws that hold the motor cover
in place. Lift the cover, and put it and the
screws aside. Use avacuum attachment or hand vacuum
to clean the
exposed elevation assembly, drive motor, lower electronics and the

surrounding areas.
Also use adry cloth for the areas that you canItreach with the vacuum cleaner. If the
machine has not been used for some time or is excessively dirty, use adry cloth to wipe
all exposed areas. Replace the cover and screws when finished.
Four Times Per Year -Clean the belt and the deck surfaces to minimize the effect of
friction between the wood deck and the running belt. Clean the underside of the running
belt and the top of the running deck surface by wiping them with aclean dry towel. Th is
should be done four times per year to prevent premature wear of the deck, running belt,
and the drive motor system.
As Needed -The running belt may become loose and slip on the drive roller with each
foot plant.
To Re-tension the Belt: While holding down any key on the console, turn the treadmill on;
this brings you into Test Mode. Press Speed ... to increase the belt speed to 5mph
(8 kph). Rotate both of the rear roller tension bolts 1/4 of aturn clockwise. If the belt
tracks off center, to either side, the running deck will become visible. If this occurs, it will
be necessary to adjust the running belt back to the center. See Figure
1.
Figure 1
!CAUTION: Be careful not to over tighten the belt. Over tightening the belt can
create excessive tension on the front
and rear rollers.
To Re-center the Belt: Use awrench to tighten the rear roller bolt on the side of the
treadmill towards which the belt
is moving. For example: If the belt moves to the right and
the deck becomes exposed on the left, use awrench to tighten the rear roller bolt on the
right side
of the frame, tighten about 1/2 of aturn (clockwise) and wait 30 seconds. If the
belt does not move back to the center
of the treadmill, make another adjustment to the
same bolt. Once the running belt has been adjusted closer to the center of the treadmill
use about 1/4 of aturn until the belt has been stabilized.
!CAUTION: While centering the belt choose one bolt to adjust. Do not adjust both
bolts.
After the belt has been centered, check the belt tension. Make sure the running belt tension is
tight enough so that the belt does not slip or hesitate when stepped on. Walk on the treadmill
at 3.5-4 mph (5.6-6.4
kph) and every 4th to 5th step throw your weight into your step to feel if
the belt is slipping. If the belt does slip, use awrench to equally tighten both rear roller

Cybex 600T Treadmill service Manual
adjustment bolts 1/2 of aturn (clockwise). Adjust the belt until no further
slipping is felt.
Running Belt Maintenance
The running belt and deck should be checked periodically for any excessive
wear. The belt may need minor adjustments. Use the following section
to help
keep your
BOOT operating properly.
Checking the Belt and Deck Surfaces -In an effort to make sure that the
running belt operates properly, visually inspect the belt on aweekly basis to
make sure that there are no tears
or fraying in the belt material.
To inspect the edges of the belt, it is necessary to remove the plastic side rails.
Follow these steps:
1. Turn the power off.
A. Turn the main power switch on the front panel to the off (0) position.
B. Unplug the treadmill from the power outlet.
!WARNING: When removing or installing the side rails be sure to wear
work gloves to protect against any sharp edges.
2. Remove the plastic end caps and side rails.
A. Remove the Phillips head screws that fasten each of the plastic end
caps
in place and set aside. See Figure 2.
B. Grab the side rail and firmly slide it out towards the back of the
treadmill.

C. Remove the other side rail and set aside.
3.
Check belt condition.
A. Run your hand under the belt on the top of the deck surface. If you notice any
excessive ridges, furrowing or cracks
in the deck or if the deck feels very rough,
the surface may have worn down to apoint where it could start to cause excessive
wear to the undersurface of the running belt. For running belt replacement
information see Running Belt
in the Removal and Replacement chapter.
4. Replace the side rails and plastic end caps.
A. Slide the two side rails back
on being sure to catch the rail guides.
B. Attach the plastic end caps with the Phillips screwdriver.
NOTE: For running belt replacement information see Running Belt in the Removal and
Replacement chapter.
!CAUTION: Do not use a running belt made for a different model treadmill. The
belts are specific for each treadmill and may be torn up or cause
excessive current and damage the electronics if used in combination
with another deck.
Rotating the Deck - You may rotate the deck but do not flip the deck. The wax surface
is only on the top side of the deck.
Do not rotate the belt. The belt is directional. See
Running Belt and Running Deck
in the Removal and Replacement chapter.
Belt and Deck Surfaces - To minimize the effect of friction between the deck and the
running belt, Cybex recommends cleaning the underside
of the running belt and the top
on the running deck surface by wiping them with aclean, dry towel. This simple
procedure should be done approximately four times ayear to prevent premature wear of
the deck, running belt and the drive motor system.
